The influence of dietary intakes during I and III trimester of pregnancy on iron status and anemia incidence [correction of prevalence] in 44 healthy pregnant women were studied. For evaluation of iron intake the probability approach calculations were used. Iron status was assessed by using multiple criteria--iron in serum, TIBC, transferrin saturation capacity and hemoglobin level. Iron deficient anemia is diagnosed in pregnant woman when hemoglobin level is less than 110 g/l and the least two of the other indices are abnormal. More than 70% of the women studied have low dietary intake of iron during pregnancy, but only 21% are anemic. The half of women with anemia are with iron deficient anemia. The results of iron intake may overestimate the risk of developing iron deficiency. Iron status during pregnancy is influenced by the dietary intake and diet structure, iron body stores and adaptive mechanisms.
研究了44名健康孕妇在妊娠第一和第三阶段的饮食摄入对铁状态及贫血发生率[患病率校正]的影响。为评估铁摄入量，采用了概率法计算。通过多种标准评估铁状态——血清铁、总铁结合力、转铁蛋白饱和能力和血红蛋白水平。当孕妇血红蛋白水平低于110g/L且其他指标中至少两项异常时，诊断为缺铁性贫血。超过70%的研究对象在孕期饮食中铁摄入量较低，但只有21%贫血。贫血女性中有一半为缺铁性贫血。铁摄入量的结果可能高估了缺铁风险。孕期的铁状态受饮食摄入、饮食结构、体内铁储备和适应机制的影响。
